Review on 🏎️ Silver Lever Type Racing Brake Bias Adjuster - Hypertune Adjustable Proportional Valve for Optimal Braking Performance by Brian Samuel

I used this to replace F100 rear disc brakes to add rear brake adjustment. The rear seemed to lock up at first but when I went to check and adjust the brakes the rear lines were damaged after the initial adjustment and I had no pressure in the rear. It was obvious. The valve stem seal (small in the photo) was partially clogged by one of the inside seams. I believe this to be a design issue and not a defective part as I can only get 800psi on the rear brakes and under the 1000psi rating with my master cylinder setup. I've included an exploded view because I'd like to see it before I get this thing. I wasn't impressed with either the design or the quality of the parts. Too bad I spent $20 on a critical system component like the brakes lol. Spending more money on better parts, that's my 2 cents.
